COIN-ADDING MACHINE.

Be it' known thatI, JOHN a citizen of theUnitedStates, residin field and State of onnecticut, haveinvented certain newfand usefulflmpro'vements in Coin-Adding Machines; and I do declareYthe following to be a full, clear, and exact description" of the invention, such as will enable others skilled in the. art to which it appertains tomake and use the Same") I a I This invention relates to certainnew and useful improvements in a coin register especially designed for small savings banks, and it has for its principal object toprovide a" simply; constructed mechanism of the coin-connectorltype' wherein the coin receiver and holder ism'oved'from its receiving positionfto its depositing position and "during such movement or actuation the registry fer addingmechanism is'coupled therewith by the coin for variable degrees ofmovementfdetermined by the denomination o'fthecoinp Iiuither, the invention resides in the novel features of construction and the ar ran ements'andlcombinations of parts here ina ferdescribed and claimed, reference being made to the. accompanying drawing wherein-' 1 p s Figure 1' a; front elevation of a coin register embodying the'present invention the casingbeing broken away to show more clearly the inclosed' mechanism;

The dollars drum may be coupled in any sultable manner with the drum 5 so as to register -every complete revolution thereof. o

The tens drum, by reason of its frictional,

telescopic relation with the units drum, ro-

tates freely therewith in a progressive man'- ner but'r'etrograde movement of drum 5 is prevented by a'spring pawl 9.,upstanding from the base 1 and engaging ina series of holes'or' depressions 1O abouttheperi 'hery' of said drum 5; Consequently, oscil ation of the inner drum will impart only pro-- gressive motion to the outer drum in an -in-] termittent manner.

Fixed on' the shaft 3. adjacent the units- :drum is a coin chute 11 having an expansi- I ble section 12 pivotedthereto at its lower end and yieldablyurged intocontracted' relation therewith 'by a'spring l3 interposed on the, shaft between said section and the fixed manipulatinglever 14. 7 The inner end of the chute lies parallel with the outer side face ofthe inner drum and is provided with transverse slots or openings 15'through which coupler pins 16 ,"fixed' on' the drum,"

may: readily except when obstructed by a depositedcoin 17. The chute'is formed so; as to arrest a coin of predetermined value opposite therespective s1ot .15',and the arrested coin will 'then,upon movement of i the handle 14 and chute 11, engage the corresponding drum pin 16 to carry the drum" along therewith fora predetermined move-1 ment. At the end of this movement the coin will be released by opening or eXpand-' ing movement'of the chute section 12. To

effect this release movement, the upper'end of said sectionis formed-with'a right angular, cam projection 18 which is adapted, to ride on a fixed abutment 19 upstanding from the base an'd shift the'chute section away from the chute and against the com.- pression'of the coiled'spring" 13 The coin thus released Willslideout' through the in;

verted upper end of the chute into the coin chamber below. The handle is then raised or retracted and in so doing brings the chute against a stop pin 20 on the inner drum which returns the latter to normal position while the outer drum is retained in its newly advanced position by the spring pawl 9.

While the registering device can be constructed for registering all denominations of coins from one cent upward, the embodiment here depicted is designed for registering only three denominations, namely nickels, dimes and quarters. The lowermost slot in the chute is covered by the dime, the uppermost by the quarter, and the inter- In operation, when one of the three coins named is placed in the chute and the shaft rotated, the coin will block its slot 15 and strike against its corresponding coupler pin or peg to thereby revolve the inner drum and simultaneously revolve the outer drtun, owing to the frictional engagement therebetween. The spring pawl is inclined on the under side so as to readily yield and permit con- 7 current rotation of the drums. The downward movement of the handle is continued until the cam member on the chute engages and rides on the abutment which will spread the chute members and release the coin to drop into the bank.

Now, with the lever forced down to its limit and the coin discharged, the pawl 9 will just be leaving one of the notches 10, but on the return or upward movement of the lever this pawl will instantly reengage in the notches as soon as the chute has abutted against the stop pin 20. Continued return of the lever to its normal position will cause this pin :20 to'revolve the inner drum independently against its frictional resistance, the outer drum meanwhile being held back by the spring pawl.

The chute, for registering a nickel, will, of course, have a greater are of free movement than for coins of higher denominations. The coin is resiliently grasped by the expansible chute and is also secured therein by the coupling pin. The construction is exceedingly simple and accurate in operation, the size of the coin determining the degree of movement of the drums which is a positive movement controlled throughout by the coin coupling. Obviously, the casing will have a coin-insert slot as shown, beneath which the chute normally returns and is disposed.

lVhat is claimed is:

1. A coin register comprising a shaft, an inner drum loose thereon, an outer drum also loose thereon and frictionally receiving the first drum whereby the two drums will rotate as a unit, said drums bearing monetary values on their peripheries and the outer drum having peripheral series of recesses, a pawl cooperating with the recesses to hold the outer drum against retrograde action, and means on the inner drum for selective engagement to rotate the same.

2. A coin register comprising a shaft, an inner drum loose thereon, an outer drum also loose thereon and frictionally receiving the first drum whereby the two driuns will rotate as 'a unit, said drums bearing monetary values on their peripheries and the outer drum having peripheral series of recesses, a pawl cooperating with the recesses to hold the outer drum against retrograde action, a coin chute mounted on the shaft alongside the adjacent side face of the inner drum and provided with a plurality of transverse edge slots, and coupler pins fixed on the side face of the inner drum each in an are including a slot of the chute whereby the empty slot may pass over the respective pin.

3. A coin register comprising a shaft, an inner drum loose thereon, an outer drum also loose thereon and frictionally receiving the first drum whereby the two drums will rotate as a unit, said drums bearing monetary values on their peripheries. and the outer drum having peripheral series of recesses, a pawl cooperating with the recesses to hold the outer drum against retrograde action, a coin chute mounted on the shaft alongside the adjacent side face of the inner drum and provided with a plurality of transverse edge slots, a coupler pin fixed on the side face of the inner drum for each chute slot for passing therethrough and adapted to be coupled to the chute by a coin blocking the respective slot, and means for effecting release of a coin from the chute.

l. In a coin register, a shaft, drums thereon bearin monetary values, a coin chute composed of two members pivoted together at one end and formed to receive a coin in their opposite ends, means to mount said members on the shaft, spring means for nor mally urging the two members together, means to coin-couple the chute to the drums, and means for moving the members apart to release the coin and to allow same to gravitate out of the said opposite ends of the members upon the members reaching a predetermined position.

5. In a coin register, a shaft, drums thereon hearing monetary values, a coin chute composed of two channeled members pivoted together at one end and having their channels confronting each other and connected to the shaft between their ends, a cam on one member, a fixed abutment for engagement with the cam to move the members apart and thereby release the coin, means to coin-couple the chute to the drums, and a coil springon the shaft engaged with one of the members to urge same toward the other member.

6. In a, coin register, a, shaft, drums therechute to the drums, and means to move the on bearingmonetary values, a coin chute members relatively apart to thereby release composed of a air of members formed to the coin therefrom, upon the chute reaching 10 receive a coin t erebetween, means to cona liredetermined osition.
